About this map

The Mississippi River defines the western edge of this landscape at Twelvemile Point, where the low-lying terrain of Plaquemines and St. Bernard Parishes meets a complex network of drainage and industrial waterways. Settled areas like Saint Clair, Scarsdale, and Caernarvon sit along the river's natural levee, while the interior is dominated by vast wetlands, including Cane Ridge Slough and the expansive waters of Big Mar. Evidence of the region's hydrological history is clear in the Caernarvon Crevasse and Paydras Crevasse, marking points where the river once breached its banks. Genealogy and local history researchers can identify established burial sites such as English Turn Cem and Scarsdale Cem, alongside industrial features like the Braithwaite Canal and Port Nickel that reflect the area's economic ties to the river.
